I took confirmation images (120 sec x5 in V) of PSN J23441603+1046125 with 0.32m f8 asrograph + SBIG STL-6303E CCD at Nerpio, Spain (iTelescope.NET), remotely. I could clearly see PSN on my image compared with DSS. Photometric result was 15.78V. Position end figures are 15.99 and 11.84 (2000.0).

Mag.=16.1U, position end figures 16s.03, 12".1, on an image composed from 3-frames which were taken by each 120-seconds exposure under the limiting magnitude = 19.3, remotely using a 0.43-m f/6.8 astrograph + CCD (SBIG STL-11000M) at the iTelescopeNET AstroCamp Observatory, Nerpio, Spain. Observer T. Yusa, Osaki, Japan. An image was posted at URL http://space.geocities.jp/yusastar77/supernova/PSNin7742_140903.htm
